What is a gigawatt used for?

A gigawatt measures large power outputs and is commonly used for rating output of big power plants and national electricity generation capacities.

Where is femtowatt measurement applicable?

Femtowatt is used to quantify very low power levels in fields like radio astronomy, photodetection, and nanoscale electronic devices.

Why is converting between GW and fW important?

It relates very large industrial power values to extremely small scientific power signals, facilitating analysis across broad power scales.
